Application filed April 9,

This invention relates to protecting devices for use on eyeleting andlike machines and the primary object is to prevent operation of themachine until the material is properly located thus preventing injury totached to machines of ordinary construction without requiring alterationof such machines.

A selected embodiment of the invention is illustrated in theaccompanying drawing,

" and therein,

Fig. 1 is a perspective View of an eyeleting machine embodying apreferred form of construction of our invention;

Fig. 2 is a view partly in vertical section and partly in elevationlooking in at the left hand side of Fig. 1; and

Fig. 3 is a sectional view taken substantially on the line 33 of Fig. 2.

In the drawing, 1 indicates the standard of an eyeleting machine havingarms 2 and 3 extending therefrom and including a base 4. At the end ofthe arm 2 is a sleeve 5 having a plunger 6 mounted for verticalreciprocation therein. At the lower end of the plunger 6 the top set 7is mounted which set includes a locating pin 8 having a head 9 arranged.in a recess 10 in the set 7 in which recess a spring 11 is mounted whichacts on the head 9 to urge the pin 8 outwardly of the end. of thespindle. At the outer end of the arm 3 a socket 12 is formed having anaxial opening 13 therein, into the lower end of which opening thelocating screw 14 is extended. The bottom set 15 includes a stemextended through a reduced portion of the opening 13 into engagementwith the inner end of the locating screw 1 At the upper end of thesocket 12 is a holder 16 for the bottom set 15. The sets 7 and 15 are arranged in vertical alinement and when the plunger 6 is moved downwardlythe eyeleting operation is carri d out by these sets in the manner wellunderstood, the material to be operated on having been previouslydisposed between these top and bottom sets.

drive shaft 17 is journaled in the standard I 1 and freely rotatablethereon is the drive pulley 18 retained between the collars 19 and 20fixed to the shaft 17. In the collar 20 is a pocket 21 and an opening 22communicates therewith. A rod 23 extends through the opening 22 into thepocket 21 and has a guide collar 24 thereon. A spring 25 is dis posedaround the rod 23 between the bottom of the pocket and the guide collar2%. At the outer end of the rod 23 and unitary therewith is a surfacecam 26 having a notch 27 therein. Bearings 28 and 29 have an operatingrod 30 extended therethrough on which rod a collar 31 is secured belowthe bearing 28. A coil spring 32 is disposed around the rod 30 betweenthe bearing 29 and the collar 31 and normally urges the collar intoengagement with the bearing 28. The pocket 21 and, therefore, the rod 23are radially located with respect to the shaft 17 and an opening 33 inthe pulley 18 is correspondingly radially located from the shaft 17.Suitable means are provided for moving the rod 30 downwardly to retractthe upper end of 1 the rod from the notch 27. The spring 25 acts on thecollar 2% and moves the rod to- .ward the pulley 18 and when the opening33 moves into alinement with the rod 23 the end of the rod 23 enters thepocket 33 and interconnects the collar 20 and the pulley 18 and,therefore, the shaft 17 and the cam 26 will be rotated. As soon as thecam 26 begins to rotate the rod 30 is released and the spring 32 forcesit upwardly into engagement with the periphery of the cam 26. .Vhen theend 34 of the cam 26 passes the rod 30 it moves upwardly until thecollar 31 abuts the bearing 28. The upper end of the rod 30 will thenlie in the path of the cam 26. Continued rotation brings the lowestpoint 35 of the cam 26 into engagement with the rod 30 and theinclination of the cam will, during continued rotation. cause said camto be moved away from the collar 30 which will retract the end of therod 23 from the opening 33 thus disconnecting the device from the pulley18. Immediately after retraction of the rod 23 from the opening 33 therod 30 will drop into the notch 27 and arrest further movement, thisaction being aided by braking devices commonly used in machines of thischaracter. At the end of the drive shaft 17 opposite the pulley 18 is alink 37 connected to a link 38 attached by a toggle connection 39 to theupper end of the plunger 6. lVhen the main shaft 17 is rotated theplunger 6 will be reciprocated. Our protecting device is adapted toprevent move ment of the rod until the material is properly locatedbetween the top and bottom sets. A collar 40 is secured at the end ofthe lever 41 and has an opening therein surrounded by the flange 42. 15is alined with the opening in the collar 40. Secured to the standard 1is an angle bracket 43 having a hinge structure 44 thereon providing afulcrum for the lever 41. At the end of the lever 41 opposite the collar40 is a lever arm 45 the end of which is disposed below the collar 31. Aspring 46 is connected to the lever 41 between the fulcrum and the leverarm 45 and acts on the lever to urge the collar 40 upwardly. The actionof the spring 46 is limited by a suitable stop which, in the presentinstance, is provided by the bearing 29 against which the end of thelever rests. The material is indicated by 47 and has an opening 48therein in which an eyelet is to be installed. The material 47 is restedon the flange 42 and pressure is applied to pivot the lever 41downwardly. If the opening 48 is properly alined with the bottom set 15this bottom set will enter the opening 48 and permit the lever 41 to bepivoted sufficiently to retract the arm 45 from below the collar 31, asshown in dotted lines in Fig. 3. If, however, the opening 48 and thebottom set 15 are not properly alined the engagement between the bottomset and the material 47 will prevent downward movement of the lever 41and, therefore, the arm 45 will remain below the collar 31 to preventdownward movement thereof and, therefore, downward movement of the rod30. It is, there fore, apparent that proper alinement of the bottom set15 and the opening in the material to receive an eyelet must beestablished be fore the machine can be operated. This will preventdamage to the material by operation of the machine when the material isnot properly alined with the sets.

While we have illustrated and described a selected embodiment of ourinvention, it is to be understood that this is capable of modificationand changes in construction without departing from the purview of thefollowing claims.
